This model is the further development of a … WebMost importantly, it can be shown that the application of a Hill-type muscle model could improve biomechanical stability. An antagonistic pair of our muscle model theoretically shows a first demonstration of how an artificial muscle could help in the stabilisation of a technical machine. As a result, the control of an inverted pendulum can be ...
WebFeb 1, 2024 · The use of simple Hill-type models in simulations, instead of more recent cross-bridge models, is well justified since computationally ‘light-weight’—although less accurate—Hill-type models have great value for large-scale simulations. However, this article aims to invite discussion on numerical instability issues of Hill-type muscle ... WebJan 23, 2024 · Computational cost of the Huxley-type cross-bridge model was much higher than that of the Hill-type model. Compared to the Hill-type model, the number of state variables per muscle was large (2 vs about 18,000), the integration step size had to be about 100 times smaller, and the computational cost per integration step was about 100 times …
WebDec 18, 2024 · Skeletal muscles are always embedded in sheets of connective tissues, which influences muscle biomechanics by shaping the fascicle geometry and encapsulating muscular mass flow. However, existing Hill-type muscle models typically take surrounding tissues into account as a nonlinear spring, without consideration of the muscle geometry … WebApr 14, 2024 · The VEXAT model more accurately captures the impedance of biological muscle and its responses to long active stretches than a Hill-type model while still retaining the ability to replicate the force-velocity and force-length properties of muscle. While the comparison between the VEXAT model and biological muscle is favorable, there are some …
